Integration Lead

Responsibilities:

• Own the integration architecture and register for the full estate — Business Central, Entra ID, Microsoft CSP, DattoRMM/BDCR, IT Glue, telephony, calendars, Power BI and Rewst.
• Direct and validate the PSA–Business Central billing feed built by the PSA vendor and Adega: customer and invoice sync, payment-status write-back, credit notes, per-customer VAT, multi-currency, payment terms; prove it by proof of concept and build the reconciliation controls Finance will accept and operate. Delivery accountability for the feed sits with the PSA and Adega.
• Upstream billing dependencies stay with their owners: PSA configuration (Configuration Lead); customer and contract data (function heads); accounting treatment (Finance); Business Central configuration (Adega); time and consumption data (Service); reconciliation operation (Finance).
• Assure the migration technically — the PSA executes transformation to the mapping specification, staged loads, delta syncs and out-of-hours final syncs; this role directs the mapping inputs, supplies and cleanses source extracts through the data administrator, and reconciles every load by counts and values. Content acceptance: function heads.
• Direct and validate identity and access — Entra ID SSO and agent and user sync, built by the PSA under the default position; own technical enforcement of the Configuration Lead’s security design.
• Direct and validate the commercial feeds the business case depends on — dynamic seat counts from DattoRMM and CSP into contracts, driving consumption billing and true-ups — built by the PSA under the default position.
• Direct and validate the operational integrations — alert-to-ticket, IT Glue knowledge, telephony screen-pop, calendars — built by the PSA under the default position; any exclusion settled and priced at scoping.
• Govern change promotion across the environments, PSA provides and operates — production, test, build sandbox; nothing untested reaches production.
• Provide the Automation Team platform access, APIs and standards; keep Rewst running through transition and support its migration to the PSA, including the PSA vendor’s contracted phase-1 runbooks — design and build sit with the team.
• Document to a supportable standard; hand over to the platform administrator, Automation Team and IT.

Requirements:

• Hands-on integration delivery: REST APIs, webhooks, middleware or scripted integration (PowerShell, Python), authentication (OAuth, Entra app registrations), error handling — has shipped production integrations.
• Data migration delivery on live systems: extraction, transformation, staging, reconciliation and cutover syncs.
• MSP tooling fluency — PSA, RMM, M365/CSP, Entra ID, IT Glue — plus working understanding of finance data: invoices, credit notes, VAT, currencies, why the ledger is the system of record.
• Automation-platform familiarity (Rewst, Power Automate); disciplined habits: environment separation, version control, documentation, monitoring.
• Directing and validating vendor engineers matters as much as personal build speed — New PSA carries substantial build.

Benefits:

• Generous professional development budget.
• Company Pension. 
• Health Plan.
• Wellness Benefit. 
• On-site Gym.
• Health & Fitness Benefit.
• Employee Assistance Program.
• Company Events.
